Piecuch, of Grand Ledge, is charged with carelessly discharging a firearm causing property damage from a March 6 incident at Brewstirs, 10745 48th Ave.

She was arraigned Friday on the misdemeanor charge, which carries a potential one year in jail.

Court records show she posted a $200 bond. As part of her bond conditions, she cannot consume alcohol and must submit to an alcohol or drug test upon the request of authorities.

Police said Guerrero's weapon, a Smith & Wesson .38-caliber pistol, was fired about 1 a.m. after Piecuch reportedly found it inside the men's bathroom, where she had gone because the line for the women's restroom was too long.

The bullet went through a bathroom wall and into a beer cooler. No one was injured.

She was not with Guerrero that night, and they do not know each other, police said.

Guerrero, 40, is charged with recklessly handling a firearm and carrying a concealed weapon while having a blood-alcohol content. The alleged offenses could land him in jail but do not threaten his state certification. At most, Guerrero could face up to 90 days in jail.

Investigators have not revealed the officer's alleged blood-alcohol content, but the civil infraction charge against Guerrero indicates his level was between .02 percent and .07 percent, according to state carrying-under-the-influence laws.

He remains on paid leave from the city force.

Guerrero who lives nearby, was off-duty and not at the bar when his gun was fired, sources said.

Employees alerted him to the fact that a woman found and shot his gun.

Guerrero, who has been on the force since 2001, returned to the bar, retrieved the weapon and left.

Sheriff's investigators could not immediately locate him after the incident.
